Underage Disney XD Star Billy Unger Arrested for Drunk Driving

It seems like one of TV's Lab Rats was experimenting a little heavily over the weekend. Billy Unger, the 18-year-old star of Disney XD's Lab Rats, was arrested for driving under the influence on Saturday, TMZ reports.

Unger was driving on the Pacific Coast Highway in Malibu, Calif., early Saturday morning when he was pulled over for speeding. When given a sobriety test, the actor recorded a .08 blood alcohol level, which is right at the state's legal limit. However, because Unger is under the legal age to drink alcohol in California, he was automatically arrested. He has since been released from jail.

Unger has played Chase Davenport in Lab Rats since the Disney XD series' debut in 2012. Lab Rats is the most watched show on the network.

Disney stars have had a rough time with alcohol and substance abuse problems. Zac Efron, Christina Aguilera, Britney Spears, Shia LeBeouf, and Lindsay Lohan are a few Disney grads who have struggled with addiction problems.
